I'm a big believer in KT tape. I use it on my ankle, peroneal tendon, achilles, and IT band. (I'm very pretty with all my pink tape.) There are instructions on their website for taping a quad strain. This might help if you aren't 100% by race day. But, you are making the right choice to rest and wait. I really wish I had done that when I first got injured three years ago. If I had, I probably wouldn't need to be a walking advertisement for KT tape.
